MRB is used for the WIN platform
GPT is mainly used for Mac (Apple),
The relationship between MBR partition tables and GPT partition tables

GPT disk partition style supports a maximum volume of 2 TB (Terabytes) and a maximum of 4 primary partitions per disk (or 3 primary partitions, 1 extended partition, and unlimited logical drives), GPT disk partition style supports a maximum volume of 18 EB (Exabytes) and there is no upper limit on the number of partitions per disk, only limited by the operating system (since the partition table itself needs to take up a certain amount of space, when initially planning the hard disk partition, The space left for partition tables determines how many partitions can be up to 128, which is also the minimum size of partition tables specified by the EFI standard). Unlike MBR-partitioned disks, critical platform operations data is located in partitions, not in non-partitioned or hidden sectors. In addition, GPT partition disk has backup partition tables to improve the integrity of partitioned data structure.
